Shape-memory polymer composites (SMPCs) with multi-capabilities have attracted growing attention in both academia and industry. However, the known fillers suffer from the deficient functionalization, which would limit the compatible capabilities and applications. Herein, we report the manufacturing of SMPCs based on the hydrogen bonding between nitrate groups from Sm(TTA)Phen(NO3)3 (STPN) and carboxyl groups from crosslinked poly(methyl methacrylate-co-itaconic acid) (P(MMA-co-IA)). SMPCs were prepared by immersing P(MMA-co-IA) in STPN solution with the concentrations of 0.001–0.03 mol L−1. The dispersion of STPN in P(MMA-co-IA) was highly improved in comparison with the rare earth organic complex of Sm(TTA)3Phen without hydrogen bonding. By employing STPN, the flexural modulus and strength were increased by 2.5 and 3.9 times, respectively. The properties of good transparency, fluorescence and near-infrared light induced shape-recovery were also achieved. This work provides an approach to prepare novel SMPCs with different properties including high strength, fluorescence, and light-induced shape-recovery.
